Essick found a lot of e-waste in Ghana, with thousands of old computers in the local markets. Here, the sellers resell a few computers, but they can t sell many because a lot of them don t work.

A: How much paper do you throw away every week? B: I don t throw away any paper. We recycle it in special green bins.

One day, he was reading some information about all the plastic in the seas and oceans. He couldn t believe what he was reading. or example, humans throw away four out of every five plastic bottles they use, and plastic trash causes about eighty percent of the pollution in the ocean. In addition, scientists think that around one million seabirds die every year from plastic pollution. De Rothschild decided he wanted to get involved in the fight against ocean pollution. o help more people understand the problem, he started building a boat made of plastic bottles. he journey 0 De Rothschild sailed the Plastiki across the Pacific Ocean from San rancisco to Sydney. hat s more than fifteen thousand kilometers. On the way, he took the special boat through the Great Garbage Patch. his is a huge area in the Pacific with. billion kilograms of trash. You can see every kind of human trash here, but the worst problem is the plastic. It kills birds and ocean life. How well did the Plastiki survive the journey? 0 my 6 Work in groups and discuss these questions. In addition to building the boat with recycled plastic, it was important to make the boat environmentally friendly and user-friendly. he boat uses renewable energy, such as wind power and solar energy. he crew can make meals with vegetables from the small garden at the back of the boat. hey can take a break from work and get some exercise by using the special exercise bicycle. he energy from the bike provides power for the boat s computers. And if anyone needs to take a shower, the boat s shower uses saltwater from the ocean. he journey wasn t always easy, and de Rothschild and his crew had to take care during storms. here were giant ocean waves, and winds of over one hundred kilometers per hour. he whole journey took one hundred and twenty-nine days. Originally, de Rothschild thought the boat could only travel once, but it lasted so well that he is planning to sail it again one day. Do you think environmental projects like the Plastiki can make people change their behavior? Why or why not? In your country, does anyone try to change people s behavior in these areas? How do they do this? recycling more trash stopping smoking driving over the speed limit eating too much food anything else? he government tries to stop people from smoking cigarettes by... knot (n) /nɒt/ a measurement of speed at sea ( knot =.8 km/hr) Unit he environment 6
